I understand that there are machines with multiple PCI busses out there but comparing the ppc64 code with the proposed mips patches I don't see much difference. Are the ppc64 people just breaking multiple PCI bus machines, did something happen in the generic PCI code which fixed the issue or is there just a difference I can't see? Cheers, Scott |
